Re: New Topic Notification
Did you try installing it? Since bbPress is beta software and has undergone lots of changes in the past year, a lot of the early plugins don’t work without modification.
There was a reply recently by sambauers about subscribing yourself to the new posts feed and front page feed (I think) via an RSS to email service like Feedblitz. Then you could get notification in your email rather than RSS.
I think the creators of bbPress have gone down the path of RSS rather than email, for notifications. Adding back in the functionality for delivery via email is most likely going to always be via a plugin. Just my opinion.
